Decent product, overpriced

I received a sample of this product in the mail. It does not lather as heavily as other shampoos, so instinctually you want to use more of it, but it isn’t really necessary. My hair felt very very clean after.
Thank being said I didn’t notice much difference in the controllability or frizz to my hair. Perhaps after long term use I would notice a difference, but for the price point of this product I am not willing to buy it to find out
